| Engine And Engine Cooling problems |
I recently purchased this vehicle, and within weeks it began experiencing intermittent and complete failure to start. The most serious incident happened in phoenix at a walmart parking lot. The vehicle refused to start at around 10 pm, and I was stranded with my daughter until 1 am in the middle of a severe storm. The vehicle would not crank, would not click, and gave no warning lights before the failure. We were stuck inside the vehicle with no ability to move it to safety. This created a dangerous situation because we were exposed to lightning, heavy rain, and unsafe conditions in a dark parking lot late at night. If the vehicle had failed in traffic or on the highway, it could have caused an accident or left us trapped in a hazardous location. The failure is unpredictable and has happened multiple times, making the vehicle unreliable and unsafe to operate. The symptoms match known electrical defects documented in Infiniti/Nissan technical service bulletins, including ipdm failure, bcm communication faults, ecm relay malfunction, starter relay issues, and can communication errors. These failures can disable the vehicle without warning and prevent it from starting for extended periods. I am requesting an investigation into electrical system defects for this model year and VIN because this issue poses a serious safety risk to me, my child, and other drivers.
